As seen in the attached screenshot, I set a route for 2C36 in the Up direction on the Reversible Line. When I did this, the previous train still occupied the TC past signal W8 (cannot remember if the TC in front of the signal was still occupied). The route did not visibly set but no message was displayed at all.When the train cleared the overlap signal W8, signal W912 suddenly turned yellow as if the route was set after all.It has happened me multiple times, I hope it is reproducible.Apart from this, I do not have problems with the Waterloo sim.I can provide a saved game 1 minute before this happened, if you want.Post has attachments.
